Abstract: Nopyl acetate was synthesized by nopol and acetic acid under microwave irradiation and catalyzed by solid superacid SO42-/ZrO2-TiO2. The influences of various reaction parameters, such as irradiation temperature, time, power, conditions for preparation of catalyst and catalyst dosage were investigated. Results show the proper technological conditions as follows: irradiation temperature 105℃, irradiation time 85 min, microwave power 650 W, catalyst type Ti:Zr 6:1, calcination temperature 450℃ and solid superacid dosage 2.5%(based on nopol mass). Under this condition, the yield of nopyl acetate reached 81.3%. Furthermore, the regenerated catalyst could be repeatedly used for 4 times.
Key words: nopyl acetate, SO42-/ZrO2-TiO2, microwave irradiation, catalytic synthesis
